Automatic filter cloth scraping filter

Abstract

The invention relates to an automatic filter cloth scraping filter wherein an unreeling mechanism and a reeling mechanism are mounted on a shell; filter cloth is wound on the unreeling mechanism and the reeling mechanism; a V-shaped filter cloth supporting leakage tank formed by connecting a first screen plate, a second screen plate and an arc connecting screen plate is fixed on the shell; a first chain wheel and a second chain wheel are in rotatable connection with the shell at the top end position of the first screen plate; scraping plates are mounted on chains; a chain limiting groove is formed by combining the space between the bottom end of a first limiting plate and the upper surface of the first screen plate, the space between the bottom end of a second limiting plate and the upper surface of the second screen plate and the space between the bottom end of a third limiting plate and the upper surface of the arc connecting screen plate; the middle pieces of the chains are restricted in the chain limiting groove; and the middle piece of the filter cloth is clamped between the chains in the chain limiting groove and the filter cloth supporting leakage tank. When the automatic filter cloth scraping filter is at work, all filter cloth can be used as far as possible, the filter cloth is not prone to be wasted, the blockage is not prone to happen, the filter flow rate is higher, and the degree of automation is high.

Description

technical field [0001] The invention relates to a solid-liquid separation machine, in particular to a filter cloth automatic scraping filter machine. Background technique [0002] The main technical characteristics of the traditional paper belt filter used at home and abroad are: the traditional product is generally a flat bed structure, the bed is like a cradle structure, the liquid that needs to be separated is easy to overflow, and the filter cloth is easy to block. Once blocked, The sensor will automatically extend the filter cloth (to automatically lower the water level), which is easy to waste the filter cloth and reduce the filtration flow. The traditional paper belt filter has no agitating roller and cannot roll up the used filter cloth. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an automatic filter cloth scraping machine that can use all filter cloths, is not easy to waste f...
